glibc_fault.yml

name: GLIBC fault test
# This workflow file is the same as the `Build + Test` with some key differences
# - Runs on any x86 and ARM64 runner
# - Disables the glibc jemalloc compile option
# - Enables the glibc allocator fault option
# - Disables gvisor tests to reduce stress on CI machines (tmp/shm tests overwhelm them)
# - Disables thunk tests since they are incompatible with glibc fault allocator
# - Disables ARMEmitter tests (We don't want to fault test vixl's disassembler)
